LOUIS S. FLATAU, OF ST. LOUIS, 'MISSOURI.

COFFEE-MAKER.

Specification of Letters Patent.

Patented Dec. 27, 19.10.

Application filed June 3, 1909. Serial No. 499,851. 8

To all whom it may concern:

Be it known that I, Louis S. FLATAU, a

citizen of the United States, residing at St.

a vessel or rece tacle to be used in connection with a co co pot afterthe water has been allowed to boil, and the coffee has been subjected tothe steam which heats and softens the coffee, but without causing anyodor from the coffee. After the water has boiled sufficiently, and thecoffee has become heated and softened, the receptacle is placed over thecoffee pot, and the water allowed to percolate through the coffeegrounds into the coffee pot, thereby making drip coffee.

The invention consists in certain novel features of construction andcombinations of parts which will be hereinafter described and pointedout in the claims.

In the accompanying drawings :Figure 1 is a vertical sectional viewthrough my improved coffee maker, Fig. 2 is a vertical sectional viewshowing the device applied to a cofiee pot permitting the water from thereceptacle of the maker to pass through the grounds of the coffee andinto the coffee pot, Fig. 3 is a top plan view of the perforated disk,Fig. 4 is a side View of the tray which supports the coflee within thecoffee maker or body, and Fig. 5 is a bottom view looking into thecover.

A, represents the vessel of the coffee maker which is provided with along neck 1 which is threaded by forming spiral corrugations 2, therein.A tray 3 is screwed into the neck 1, the body portion or walls of whichare spirally corrugated so that it can be easily inserted or removedfrom the neck by a handle 4, which is connected thereto. The tray ispreferably made cup-shaped, and the bottom is perforated as at 5. Thetray is adjustable within the neck, and is placed within the neck at theproper distance to receive the coffee grounds which are placed in theneck to be heated by the steam for softening the coffee before thepercolation operation. After the grounds have been placed in the neck, aperforated disk 6 is placed in the neck directly over the coffee, thenthe cover 7 is inserted into the neck by screwing the cover therein. Thewalls or body of the cover are spirally corrugated so that it can bescrewed into the neck by the handle 8 which is connected to the cover.The top of the cover is perforated at 9 to admit of the steam and waterpassing therethrough.

The disk 6, tray 5, and the cover 7 are all provided with perforations;while a Wire netting of fine and coarse mesh might be used, I prefer tosimply perforate the different members. The tube 10 is received in thevessel and extends nearly to the bottom thereof, the upper end of thetube projecting out through the vessel and extending along the neck 1,which acts as a means for permitting the steam to escape when the wateris boiling, and when the vessel is inverted for the percolationoperation. Thus the tube acts as an air-vent. A handle 11 is connectedto the vessel for lifting and movin the vessel.

lSy the adjustment of the tray 3, the coffee is held between theconfines of the cover and disk and tray against movement, that is to anygreat extent, and any quantity of cofi'ee can be made by simplyadjusting the tray within the neck of the vessel. This is consideredvery advantageous, and the fact that the cover and tray both screw intothe neck, obviates any danger of the water during the percolatingoperation, passing along the sides of the neck without coming intodirect contact with the coffee. Without the adjustable feature forconfining the coffee against movement between the cover and tray, andproviding a screw connection between the cover, tray, and neck, thewater which might pass between the neck, tray and cover might passthrough without coming in contactat all with the coffee, provided thecoffee is not held tight between the cover and tray. This wouldespecially happen when the vessel is being inverted for the percolation.After the water has boiled in the vessel A, sufficiently, and the coffeehas become steamed and softened, the neck 1 is placed within the neck ofthe coffee pot B for making drip coffee. The water 1n the vessel A, willnow pass through the erforations 5 in the tray 3, through the co cc, andthrough the disk 6 and cover 7.

The coffee maker can be made of any size and to suit the differentrequirements, and of course can be used for making boiled coffee, ifdesired, by placing the coffee and water together, and after it hasboiled sufficiently, the vessel can be inverted, and the coffee strainedthrough the tray strainer and neck into another pot, thereby strainingthe coffee thoroughly from all the grounds or dregs.

Another method of making coffee would be done by placing the tray 5 andstrainer 6 into the neck and placing the coffee upon the strainer 6,pouring water over the coffee, permitting it to pass through into vesselA and after the coffee is made, the disk and tray could be removed, andthe coffee strained through the cover 7.

Of course, there might be other methods of making coffee with thisdevice, and it is evident that more or less slight changes might beresorted to in the form and arrangement of the several parts describedwithout departing from the spirit and scope of my invention, and hence Ido not wish to limit myself to the exact construction herein set forth,but

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent, is

1. A coffee maker comprising a vessel having an extended spirallycorrugated neck, a perforated tray and a perforated top adapted to beremovably screwed into and held in the neck, and a tube which extendsfrom the interior of the vessel out alongside the neck in position toenter the coffee pot when the vessel is inverted and the neck thereof isinserted into the, top of the coffee pot.

' 2. A coffee maker comprising a vessel haves oss ing an extendedspirally corrugated neck, and a tray and top similarly corrugated toscrew into the top and bottom of the neck and held therein, said partseach having perforated heads and provided with handles to facilitateturning them in and out of the neck.

3. A coffee maker comprising a vessel having an extended screw-threadedneck, a screw-threaded tray provided with perforations adapted to, bescrewed into and held in the neck, said tray adapted to receive thecoffee, a strainer disk mounted over the coffee, and a screw-threadedcover having perforations therein adapted to screw into and held in theneck whereby the coffee is confined between the tray, strainer andcover, said vessel adapted to be inverted to permit the water from thevessel to pass through the coffee for making drip coffee.

4. A coffee maker comprising a vessel having an extended screw-threadedneck, a screw-threaded perforated tray for supporting the coffee. withinthe neck adapted to be screwed therein the required distance and held,and a screw-threaded perforated cover adapted to be screwed into andheld in the neck.

In testimony whereof I affix my signature, in the presence of twowitnesses.
